SATA Controller Cards Many workers have an ever-increasing need for more hard disk space, including IT pros, graphic designers, and video editors. Our SATA controller cards add internal Serial ATA (SATA) and external eSATA capability to your computer, through PCI. A bad hard drive cable. If the recommendations above are attempted, and you are still encountering the same issue, the cable connecting the hard drive may be bad. Replace this cable with a known good cable. If you continue to experience the same issues, the hard drive may be bad. We recommend the drive be replaced.
- SYBA SI-PEX40062 PCI-Express 2.0 x2 Low Profile Ready SATA III (6.0Gb/s) Controller Card. Internal Connectors: 4 x SATA 6.0Gb/s Transfer Rate: Up to 6Gb/s Operating Systems Supported: Windows 8 Windows 7 Vista Windows XP Server 2008 Server 2008 R2 Server 2003 Linux 2.6.x and Above (AHCI devices driver is a built-in feature) Package Contents: SATA III 4-port PCI-e Version 2, x2 Slot Controller.
- Hard disk controller, known as the adapter of hard disk driver, is the interface device between computers and hard disk driver. Hard disk controller is used to receive and interpret the computer order, and then send various control signals to hard disk adapter. Also, it detects the hard disk driver status.
- Attach a power cable (2) to the drive, and attach a data cable (3) from the SATA port or SAS controller to the hard disk drive. Caution: To avoid crushing or pinching the data cable when you replace the access panel, use a data cable with a right-angle connector when you install a HDD in bay 1 or bay 2.

The disk controller is the controllercircuit which enables the CPU to communicate with a hard disk, floppy disk or other kind of disk drive. It also provides an interface between the disk drive and the bus connecting it to the rest of the system.
Early disk controllers were identified by their storage methods and data encoding. They were typically implemented on a separate controller card. Modified frequency modulation (MFM) controllers were the most common type in small computers, used for both floppy disk and hard disk drives. Run length limited (RLL) controllers used data compression to increase storage capacity by about 50%. Priam created a proprietary storage algorithm that could double the disk storage. Shugart Associates Systems Interface (SASI) was a predecessor to SCSI.
Modern disk controllers are integrated into the disk drive as peripheral controllers. For example, disks called 'SCSI disks' have built-in SCSI controllers. In the past, before most SCSI controller functionality was implemented in a single chip, separate SCSI controllers interfaced disks to the SCSI bus.
These integrated peripheral controllers communicate with a host controller in the host system over a standardized, high-level storage bus interface. The most common types of interfaces provided nowadays by disk controllers are PATA (IDE) and Serial ATA for home use. High-end disks use Parallel SCSI, Fibre Channel or Serial Attached SCSI.
Disk controllers can also control the timing of access to flash memory which is not mechanical in nature (i.e. no physical disk).

Disk controller versus host adapter[edit]
The correct[clarification needed] term for the component that allows a computer to talk to a peripheral bus is host adapter or host bus adapter (HBA). On the other hand, a disk controller allows a disk to talk to the same bus. Those two are often confused, especially in the PC world. In fact signals read by a disk read-and-write head are converted by a disk controller, then transmitted over the peripheral bus, then converted again by the host adapter into the suitable format for the motherboard's bus, and then read by the CPU.
Sometimes there may be yet another controller between a host adapter and a disk controller - a disk array controller that allows hardware RAID to be formed. Sometimes it may be even physically integrated with an HBA, but it performs different functions.
